Answer:

The easiest way to tackle this problem is by breaking the vectors up into their components (also it's easier to type this method).

G = 40.3 cos (-35.0°) i + 40.3 sin (-35.0°) j ----where i denotes the x direction and j denotes the y direction

H = 63.3 sin (270°) j ----- I left off the i component because i know cos 270 is 0.

40.3 and 63.3 are the magnitudes of your vector, or the hypotenuse of a triangle. We are finding the horizontal (Adjacent) and vertical (Opposite) legs the respective hypotenuse (we have to remember SOH COH TOA)

Now you can simply add components

G + H = (40.3 cos (-35.0)) i + (40.3 sin (-35.0°)+ 63.3 sin (270)) j ----be sure to pay close attention to signs when doing your calculations on your calculator.

Vilka [71]

Answer:

I = 5[amp]

Explanation:

Electrical power is defined as the product of voltage by current.

P=V*I

where:

P = power = 1150 [W]

V = voltage = 230 [V]

I = current [amp]

Now replacing:

1150=230*I\\I=1150/230\\I=5[amp]

A 15 [amp] fuse must be used. Always the fuse must be larger than the operating current, to protect the equipment from very high currents. above 15 [amp]

An automobile traveling along a straight road increases its speed from 30.0 m/s to 50.0 m/s in a distance of 180 m. If the accel
inessss [21]

Answer:

4.5sec

Explanation:

From the question above, the following are the parameters that are given

u= 30m/s

v= 50m/s

s= 180m

First of all we have to find the acceleration by using the third equation of motion

V^2= U^2 + 2as

50^2= 30^2 + 2(a)(180)

2500= 900 + 360a

Collect the like terms

2500-900= 360a

1600=360a

Divide both sides by the coefficient of a which is 360

1600/360=360a/360

a= 4.44m/s

The next step is to find the time. To do this we will have to use the first equation of motion

v= u + at

50= 30 + 4.44t

Collect the like terms

50-30= 4.44t

20= 4.44t

Divide both sides by the coefficient of t which is 4.44

20/4.44= 4.44t/4.44

t= 4.5sec

Hence 4.5secs elapses while the auto moves at a distance of 180m
